    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Ester Pörtfors; Malin Svärdling; [2024]
    Keywords : Mechanical CPR; Cardiopulmonary Resuscitation; LUCAS Chest Compression System; Test Equipment; Chest Biomechanics; Chest Stiffness; Technology and Engineering;

    Abstract : The LUCAS Chest Compression System is a market leading mechanical cardiopulmonary resuscitation device, assisting medical professionals worldwide when treating patients with sudden cardiac arrest. The objective of this master thesis project was to develop a new, adjustable test equipment for the LUCAS device, allowing for tests on varying chest heights and stiffness levels. READ MORE

  3. 2. A personalized quasi-passive ankleexoskeleton using human-in-the loop optimization approaches

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Ho Ming Kong; [2023]
    Keywords : ;

    Abstract : Passive ankle exoskeletons have been proven to successfully decrease muscle demand for walking. The movement of the user’s ankle drives a mechanical clutch and spring, which eventually stores and returns mechanical energy to the user. READ MORE

    Keywords : ;

    Abstract : This master's thesis aimed to investigate the behaviour of reinforced concrete beams under dynamic loading conditions, specifically focusing on understanding shear failure. The study was conducted with KTH Royal Institute of Technology, the Swedish Fortifications Agency, and Tyréns. READ MORE

  5. 4. Hybrid bridge deck of timber and corrugated steel plates

    University essay from KTH/Byggnadsmaterial

    Author : Muze Lu; [2023]
    Keywords : ;

    Abstract : Over the years, hybrid structures composed of timber and steel have become a potential alternative to conventional solutions. Recently, corrugated steel plate (CSP) has become more and more popular in structures such as shear walls and roofs due to its favorable mechanical properties. READ MORE

  6. 5. Impact of Frame Stiffness on Tribological Behaviour of Sliding Interfaces

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Nisha Singh; [2023]
